86 THE CAYUGA FLORA. 



Field south of Indian Spring Marsh, and scattered over the Ithaca 

 plain. Occasional in the low woods throughout our territory and 

 extending to Cayuga and Montezuma Marshes. 



829. * Q. Prinus, L. Rock-Oak. CHESTNUT-OAK. (H. and C.) 

 Chiefly on banks of ravines and dry hills; frequent. May 15-30. 

 Most of our specimens have the large nuts, with turbinate cups, 



and leaves usually broad. Forms with narrow leaves and small 

 nuts occur at White Church, Fall Cr., Snyder Hill and elsewhere. 

 A form at White Church has nuts small borne on peduncles 2-3 cm. 

 long. 



830. Q. prinoides, Willd. (O. pumila, Michx.; O. Prinus, L., var. 

 kumilis, Marsh.) 1. This, the dwarf form, occurs very sparingly 

 along the east shore of the lake, north of the High Cliffs between 

 King's Fern' and Willet's. (Penn Yan, Herb. Sartwell.) 



831. 2. The arboreal form, (O. Prinus, L., var. acuminata, Michx.; 

 Q. Muhlenbergii, Engelm ; Q. Castanea Muhl.,) is also rare, on 

 limestone or in its vicinity. May 20-June I. 



On first ledge of Tulry limestone, south of Shurger's Glen, a few 

 trees. Big Gully, in ravine above the crossing of the second road 

 from the lake, a considerable number of small or middle sized trees. 

 Our trees have the characteristic bark, leaf and nut of this species. 

 I follow Prof'r Sargent in joining these two seemingly distinct 

 forms, as he has had a wide range of specimens and observations 

 on which to base his judgment. 



832. Q. coccinea, Wang. Scarlet Oak. (H. and C.J 

 Dry hills ; infrequent. May 15-25. 



Frequent on the campus, (good examples at the north entrance. ) 

 Sparingly at Six Mile Creek Narrows, and near S. S. 420, on South 

 Hill. North of .Salmon Creek, and of Lake Ridge, otherwise scarce 

 near the lake shore. Woods N. W. of Pleasant Grove Cemetery. 

 Near Junius Ponds.

834. Q. rubra, L,. Red Oak. (H. and C.) 

 The common oak of the drier woods and lake shore. May 15-25. 

 A good example occurs by the Campus Brook, at the Sage Coll. 



bridge. The leaves of this oak often change to a fine bronze and 

 brownish scarlet, as well as yellow, in the Autumn. Apparent hy- 

 brids with Q. coccinea occur on the Fiske-McGraw grounds.
